"How to add a note to an order or object" matching MCP servers:

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

An MCP server that provides authorization middleware for AI agents using private data, enabling consent management on Aleo and local private inference with persistent policy storage.

An AI-driven platform for analyzing Polymarket prediction markets using on-chain data, offering smart money tracking, sentiment analysis, and arbitrage detection via natural language queries.

Keyless CEX/DEX order signing for AI trading agents (Binance, OKX, Bybit, KuCoin, Hyperliquid, Asterdex). Exchange keys stay inside an AWS Nitro Enclave — the agent gets policy-bounded signatures, never credentials. Built to survive prompt injection and supply-chain key leaks.

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

Enables users and AI agents to verify whether a crypto recipient address is an address-poisoning lookalike or has an invalid EIP-55 checksum before sending funds, and provides access to an on-chain history scan for suspicious transfers.

Provides read-only access to Polymarket prediction markets, enabling searches, order book inspection, price history, reward market rankings, and trader activity via natural language.

Build AI trading agents on Eterna Hybrid Exchange (no-KYC perp DEX with flat 0.014%/0.035% fees). Works out of the box with fee estimation, venue comparison, setup guides and guarded agent prompts; add an Eterna token to bridge the official trading tools.

An MCP server that provides structured access to Aster DEX market data—covering candlesticks, order books, trades, and funding rates.

Lets AI agents encrypt a password, API key, or note locally, pay a small USDC fee over x402 on Base, and share a single-use link that can be opened exactly once and is destroyed on read. Reading is free, expiring unread secrets are cleaned up, and the server only ever stores ciphertext.

Enables interaction with CoW Protocol's order book API, allowing token resolution, quote retrieval, and order management across multiple networks through natural language.

Enables AI agents to directly operate ChainPay cryptocurrency payment system, including order creation, balance checks, and withdrawals.

Provides read-only access to the Hydromancer Hyperliquid API, letting AI apps query wallets, trades, top traders, markets, funding rates, order-book depth and liquidations in plain English. All requests go to the read-only /info endpoint, so it never places orders or handles funds or keys.

Enables AI assistants to query bloxberg blockchain state, explore transactions and contracts via Blockscout, and verify Research Object Certificates anchored on-chain.

A curriculum that teaches AI agents how to spend their own money. Sixteen lessons from "what is a wallet" to your first x402 purchase. Teacher, not butler — never signs, pays, or holds keys.

Keyless domain planner that connects external agents to ChainWhisper OTC trading on COTI Mainnet, allowing order preparation and validation without private keys.

Enables AI agents to browse, search, and trade on Polymarket prediction markets, including viewing markets, order books, balances, and placing/canceling orders.

Enables AI assistants to query a T-Bank (Tinkoff) investment account in read-only mode, covering accounts, portfolio and positions, operation history, instrument lookup, market data such as candles and order books, plus technical indicators, fundamentals, analyst consensus and dividend or bond coupon analytics through one-line tool calls. No tool can place trades, withdraw funds or change account settings, and a read-only API token is recommended.
